Data of Jupiter were obtained with the NASA GSFC
Acousto-optic Imaging Spectrometer (AImS) in February 2002
at the Air Force Research Laboratory's 3.67-meter AEOS
telescope. The tunable nature of AImS allows the generation
of image cubes of Jupiter over the range from 500 to 1050
nm. One of the primary goals of this data set is to
determine the spatial distribution and nature of the
coloring agents in Jupiter's atmosphere. Using principal
components analysis, the spectra can be broken into
orthogonal components mapped over the visible disk of the
planet. This method is limited by its orthogonal nature,
though, and the use of rotated components to remove this
constraint requires some a priori knowledge of the spectral
constituents. Another technique, self-organizing mapping,
sorts each pixel's spectrum and arranges them according to
those most similar to it. This technique is particularly
sensitive to end-members of the spectral distribution which
can reveal new spectral characteristics. We present here
preliminary results of our spectral analyses.
